DOST-FPRDI study shows promising health benefits of bamboo leaves

Press Releases, Science and Technology

The bamboo plant is useful beyond its poles.

A DOST-FPRDI researcher measures the phytochemical content of bamboo leaves.

Bamboo – which is a type of grass – is one amazing plant.

It is one of the fastest-growing plants in the world and is said to be the most versatile. It is so versatile, in fact, that an international research group says that bamboo has as many as two thousand documented uses.

Most Filipinos, however, know bamboo only as a source of culms for making houses, furniture, fences, baskets, barbecue and bananacue sticks, and of course, “tinikling” poles. Very few know the value of bamboo leaves.

A recent study of the DOST-Forest Products Research and Development Institute (DOST-FPRDI) will hopefully help make bamboo leaves more popular in the Philippines.

The research project, completed by the team of Ms. Mariluz SP. Dionglay, shows that the leaves of the bamboo species “kauayan-tinik” (Bambusa blumeana J.A. & J.H. Schultes) is a promising source of antioxidants, phytochemicals, and antimicrobials – and thus, is a possible raw material for medicines and nutritional supplements.

Its antioxidant potential is so high, it is similar to that of ascorbic acid which is the standard.

Phytochemicals are biologically active compounds found in plants that have health benefits to humans and animals. Plant antioxidants, on the other hand, are phytochemicals that protect the body from cell damage due to free radicals. Many bioactive plant compounds have been tapped by the pharmaceutical industry for their anti-tumor, anti-inflammatory, anti-aging and antibacterial effects.

The DOST-FPRDI project studied leaf extracts from five types of bamboo found in the Philippines. The leaves were harvested during the dry season and extracted using water and ethanol.

“Among the four species, kauayan-tinik was the most promising,” said researcher Ms. Rebecca B. Lapuz. “Kauayan-tinik leaves extracted with water had the highest phytochemical and highest antioxidant levels compared to bolo, giant bamboo, kauayan-kiling and buho. It also showed antimicrobial action against the two bacteria species studied.”

“Given these promising results, and considering the abundance of bamboo in the Philippines as well as thegiantmarket for health and wellness products here, we look forward to doing further research on kauayan-tinik leaves, as well as leaves of other Philippine bamboos,” added Lapuz.

In recent years, bamboo leaf extracts have received a lot of research attention especially in China due to their reported health benefits. (Rizalina K. Araral/ DOST-FPRDI)
